I really love taking hot showers after I come home from a run, but I always forget to turn on the vent. This is only a problem because the bathroom has no windows, and I keep the door closed so I can get the benefit of all the steam. One day, I noticed something fuzzy around the bottom of the tub and in the corners of the ceiling. This was mold. My landlord called this company (after he finished yelling at me), but made me pay for it. I was glad to learn that the prices were really reasonable, and that the company did excellent work. They had the mold out in no time, and the bathroom looked good as new!
